Transforms all passed R objects into a JSON list

Usage

formatter_json(
  ...,
  .logcall = sys.call(),
  .topcall = sys.call(-1),
  .topenv = parent.frame()
)

Arguments

...

passed to toJSON wrapped into a list

.logcall

the logging call being evaluated (useful in formatters and layouts when you want to have access to the raw, unevaluated R expression)

.topcall

R expression from which the logging function was called (useful in formatters and layouts to extract the calling function's name or arguments)

.topenv

original frame of the .topcall calling function where the formatter function will be evaluated and that is used to look up the namespace as well via logger:::top_env_name

Value

character vector

Note

This functionality depends on the jsonlite package.

This is a log_formatter() potentially to be used with layout_json_parser(), for alternatives, see formatter_paste(), formatter_sprintf(), formatter_glue(), formatter_glue_safe(), formatter_glue_or_sprintf(), formatter_logging(), formatter_pander() and skip_formatter() for marking a string not to apply the formatter on it.

Examples

if (FALSE) { # \dontrun{
log_formatter(formatter_json)
log_layout(layout_json_parser())
log_info(everything = 42)
log_info(mtcars = mtcars, species = iris$Species)
} # }
